- Abstract
- Online displays of bibliographic records in call number order can serve various functions. A literature search showed no papers or books discussing this topic directly. Various displays from online catalogues available via the Internet were examined, as were displays sent to the author by colleagues. A number of the displays were uninformative to the extent that the identification of works associated with call numbers was difficult or impossible without follow-up searching of the individual bibliographic records. Other displays provided information where further searching of the database would not be required for most purposes. Displays noted ranged from displays with call numbers alone, with no bibliographic information, to records including main entry, title, statement of responsibility, place, publisher, and date. Suggestions of useful data elements to be included in displays of bibliographic records in call number order are made for the following functions: shelflisting, cataloguing, catalogue maintenance, reference, public searches, acquisition and collection development, and inventory control. Recommendations are made that the following data elements should be present in call number displays: entire call number as a sequencing element; main entry; entire title proper, and the date. Concern is expressed that the call number filing arrangement be that followed in traditional shelflists, and a suggestion is made that possible consensus on the placement of the data elements within a display be considered in the future

- Abstract
- Much literature has been written speculating upon how classification can be used in online catalogs to improve information retrieval. While some empirical studies have been done exploring whether the direct use of traditional classification schemes designed for a manual environment is effective and efficient in the online environment, none has manipulated these manual classifications in such a w ay as to take full advantage of the power of both the classification and computer. It has been suggested by some authors, such as Wajenberg and Drabenstott, that this power could be realized if the individual components of synthesized DDC numbers could be identified and indexed. This paper looks at the feasibility of automatically decomposing DDC synthesized numbers and the implications of such decomposition for information retrieval. Based on an analysis of the instructions for synthesizing numbers in the main class Arts (700) and all DDC Tables, 17 decomposition rules were defined, 13 covering the Add Notes and four the Standard Subdivisions. 1,701 DDC synthesized numbers were decomposed by a computer system called DND (Dewey Number Decomposer), developed by the author. From the 1,701 numbers, 600 were randomly selected fo r examination by three judges, each evaluating 200 numbers. The decomposition success rate was 100% and it was concluded that synthesized DDC numbers can be accurately decomposed automatically. The study has implications for information retrieval, expert systems for assigning DDC numbers, automatic indexing, switching language development, enhancing classifiers' work, teaching library school students, and providing quality control for DDC number assignments. These implications were explored using a prototype retrieval system.

- Abstract
- Potential uses for classification data in machine readable form and reasons for the development of a standard, the USMARC Format for Classification Data, which allows for classification data to interact with other USMARC bibliographic and authority data are discussed. The development, structure, content, and use of the standard is reviewed with implementation decisions for the Library of Congress Classification scheme noted. The author examines the implementation of USMARC classification at LC, the conversion of the schedules, and the functionality of the software being used. Problems in the effort are explored, and enhancements desired for the online classification system are considered.

- Abstract
- The Library of Congress Subject Headings schema (LCSH) is by far the most commonly used and widely accepted subject vocabulary for general application. It is the de facto universal controlled vocabulary and has been a model for developing subject heading systems by many countries. However, LCSH's complex syntax and rules for constructing headings restrict its application by requiring highly skilled personnel and limit the effectiveness of automated authority control. Recent trends, driven to a large extent by the rapid growth of the Web, are forcing changes in bibliographic control systems to make them easier to use, understand, and apply, and subject headings are no exception. The purpose of adapting the LCSH with a simplified syntax to create FAST is to retain the very rich vocabulary of LCSH while making the schema easier to understand, control, apply, and use. The schema maintains upward compatibility with LCSH, and any valid set of LC subject headings can be converted to FAST headings.

- Abstract
- The scatter of items dealing with similar concepts through the physical library is a consequence of a classification process that produces a single notation to enable relative location. Compromises must be made to place an item where it is most appropriate for a given user community. No such compromise is needed with a digital library where the item can be considered to occupy a very large number of relative locations, as befits the needs of the user. Interfaces to these digital libraries can reuse the knowledge structures of their physical counterparts yet still address the problem of scatter. View-based searching is an approach that takes advantage of the knowledge structures but addresses the problem of scatter by applying a facetted approach to information retrieval. This paper describes the most recent developments in the implementation of a view-based searching system for a University Library OPAC. The user interface exploits the knowledge structures in the Dewey Decimal Classification Scheme (DDC) in navigable views with implicit Boolean searching. DDC classifies multifaceted items by building a single relative code from components. These codes may already have been combined in the schedules or be built according to well-documented instructions. Rules can be applied to decode these numbers to provide codes for each additional facet. To enhance the retrieval power of the view-based searching system, multiple facet codes are being extracted through decomposition from single Dewey Class Codes. This paper presents the results of applying automatic decomposition in respect of Geographic Area and the creation of a view (by Geographic Area) for the full collection of over 250,000 library items. This is the first step in demonstrating how the problem of scatter of subject matter across the disciplines of the Dewey Decimal Classification and the physical library collection can be addressed through the use of facets and view-based searching

- Abstract
- Describes the development by the Defence Metallurgical Research Laboratory, Hyderabad, India, of an expert system for classification of technical documents using the UDC schedule for metallurgy as knowledge base and the UDC classification rules as rule base. The scheme was modified from its enumerative structure to an analytico-synthetic structure which is best suited to such an expert system. Some benefits of the expert system are that: it interacts with the classifier making them conform to the route suggested by the classification scheme; it alerts the classifier to the minor variations in the scheme thus avoiding overlooking them; it leads to consistency in class number generation; and it ensures that the classifier has incorporated als the concepts of the subject in the class number, by leading him or her through all the groups, which is not possible in the manual scheme
